JOHN G. HARPER, OF NEW YORK, T. Y.

IMPROVED GAS-LIGHTING DEVICE.

Specification forming part of Letters Patent No. 48,932, dated July 25,1865.

To all whom it may concern Be it known that I, JOHN G. HARPER, of thecity, county, and State of New York, have invented a new and ImprovedGas-Lighting Device; and 1 do hereby declare that the following is afull, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a vertical central section of my invention, taken in theline a: a2, Fig.2; Fig. 2, a horizontal section of the same, taken inthe line 3 1 Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and useful device for lighting gas, andis more especially designed to be used for lighting street-lamps andother out-door lamps, so as to dispense with the use offriction-matches, a great number of which are consumed for this purpose011 account of failures to ignite owing to the wind, storms, dampness ofthe atmosphere, unnecessary waste, 85c.

The invention consists in inserting an oil or other lamp withinasuitable case, provided with an opening at such a point and in suchrelation with the wick-tube of the lamp that the device may be appliedto the gas-burner, and the flame from the lamp ignite the gas issuingtherefrom.

A represents a case, which may be of oylim d rical or other form, andconstructed of sheet metal. This case is provided with ahandle, B, andhas a vent at its top to admit of a draft through it to supply with airthe lamp within. The case is also provided with a door, U, for thepurpose of lighting and trimming the lamp, &c.

D is the lamp, which is of annular form, and is fitted on or around acylindrical flange, a, at the bottom of the case, said flangeencompassing a circular opening in the bottom ofthe case. The lamp isprovided with an inclined wicktube, b, the upper end of which is nearlyin line with the opening in the bottom of the case, and

is a short distance above the flange a. This lamp may be supplied withwhale-oil. I prefer that material, although others may be used.

The device is used as follows: The lamp D is filled, and its tube 1)supplied with a wick and lighted, and the door 0 closed. The flame ofthe lamp D is supplied with air through the opening in the bottom of thecase A. The bottom of the case is placed over a gas-burner, the gas leton, and the gas ascending up through the opening in the bottom of thecase is instantly ignited by contact with the flame of lamp D.

It is not essential that the gas-burner be allowed to project much upinto the flange a in order to ignite the gas, but it would be advisableto have it extend up a trifle. The work is done in a moment, and afailure need not in any case occur at the first essay or attempt.

The lamp D, it will be seen, is fully protected from the wind andwcatherequally so as the lamp in an ordinary lantern. The device willprove a very economical affair for those having contracts for lightingstreet gas-lamps, as the friction-matches now employed for that purpose,especially at the present enhanced price, are a very expensive article.Besides with my invention the work may be done more expeditiously.

I do not confine myself to the precise mode ofconstruction herein shownand described, for that may be varied or modified, and the same endattained.

Having thus described my invention, I claim as new and desire'to secureby Letters Paton t A case or jacket provided with a lamp for burning oilor other suitable material, and having an opening or aperture made in itin such a relative position with the wick-tube of the lamp as to admitof the case or jacket being applied to a gas-burner to ignite the gasissuin g therefrom, substantially as set forth.
